How to read QR codes with AIR?

[Manel_pi_ferrer]

Hello,

I need to create an AIR application developed with Adobe Animate which can read QR codes.

I found some code samples in AS3 based on "LOGOSWARE Class Library", but this only can read basic QR Codes, but not QR codes with a lot of information, such as the sample I have added in this post.

There is some other library to read QR codes? Can someone help me?

The code that I'm using looks like:

import flash.display.*;

import flash.events.*;

import flash.text.*;

import flash.media.*;

import flash.utils.*;

import flash.filters.*;

import flash.geom.*;

import flash.net.URLRequest;

import flash.net.navigateToURL;

import com.logosware.event.QRdecoderEvent;

import com.logosware.event.QRreaderEvent;

import com.logosware.utils.QRcode.GetQRimage;

import com.logosware.utils.QRcode.QRdecode;

private function onStart():void {

cameraView = buildCameraView();

resultView = buildResultView();

cameraView.x = (stageWidth - cameraView.width) / 2;

cameraView.y = -15;

this.addChild(qrHome_mc);

this.addChild( cameraView );

this.addChild( resultView );

resultView.visible = false;

getQRimage = new GetQRimage(video);

getQRimage.addEventListener(QRreaderEvent.QR_IMAGE_READ_COMPLETE, onQrImageReadComplete);

qrDecode.addEventListener(QRdecoderEvent.QR_DECODE_COMPLETE, onQrDecodeComplete);

redTimer.addEventListener(TimerEvent.TIMER_COMPLETE, onRedTimer );

this.addEventListener(Event.ENTER_FRAME, onEnterFrame);

}

private function buildCameraView():Sprite {

camera.setQuality(0, 100);

videoHolder.addChild( video );

videoHolder.x = videoHolder.y = 15;

freezeImage = new Bitmap(new BitmapData(SRC_SIZE, SRC_SIZE));

videoHolder.addChild( freezeImage );

freezeImage.visible = false;

red.graphics.lineStyle(2, 0xFF0000);

red.graphics.drawRect(videoHolder.x - 5 , videoHolder.y , videoHolder.width - videoHolder.x - 5, videoHolder.height - videoHolder.y - 10);// .drawPath(Vector.<int>([1, 2, 2, 1, 2, 2, 1, 2, 2, 1, 2, 2]), Vector.<Number>([30, 60, 30, 30, 60, 30, 290, 60, 290, 30, 260, 30, 30, 260, 30, 290, 60, 290, 290, 260, 290, 290, 260, 290]));
